Factors Associated With Acoustic Bat Presence During Spring Emergence In The Appalachian Mountains Of Western Virginia, Emily Kirk Pody
Factors Associated With Acoustic Bat Presence During Spring Emergence In The Appalachian Mountains Of Western Virginia, Emily Kirk Pody
Theses, Dissertations and Capstones
Studies of threats that bats face during hibernation have increased in response to white-nose syndrome (WNS), a fungal disease that has ravaged North American bat populations. However, impacts of WNS on bat ecology during spring emergence, when bats are potentially recovering from infection and allocating resources for reproduction, is relatively understudied. As more bat species become listed at the federal and state level, the need to understand the factors associated with spring emergence is critical for improving conservation guidelines and habitat management practices. Acoustic monitoring is an efficient method for monitoring bat presence for prolonged periods of time, giving biologists …
Factors That Influence Small Mammal Long Bone Morphology: An Analysis Of The Femora, Tibiae, And Humeri Of The Eastern Gray Squirrel (Sciurus Carolinensis), Tyler Everette Blake
Factors That Influence Small Mammal Long Bone Morphology: An Analysis Of The Femora, Tibiae, And Humeri Of The Eastern Gray Squirrel (Sciurus Carolinensis), Tyler Everette Blake
Theses, Dissertations and Capstones
The goal of this study is to examine the effect of urbanization and latitude on bone morphology, specifically limb length and bone density among gray squirrels endemic to the eastern United States. This study’s hypotheses are as follows: gray squirrels occupying lower latitudes will have larger body sizes and longer limbs relative to body size than those at higher latitudes following Bergmann’s and Allen’s rules. Further, squirrels in urban habitats will have greater bone density than those in rural habitats. Results show moderate correlation between body mass and respective proxies and latitude following Bergmann’s rule. Weak correlations were found between …
Using Occupancy Modeling For Protocol Development And Habitat Assessment Of Necturus Maculosus In A Large Nagivational River, Alyssa Rachelle Jones
Using Occupancy Modeling For Protocol Development And Habitat Assessment Of Necturus Maculosus In A Large Nagivational River, Alyssa Rachelle Jones
Theses, Dissertations and Capstones
Determining the survey effort required to reliably detect population change can be challenging for cryptic, elusive species. The secretive nature of amphibians makes it difficult to monitor population status and gather information about their natural history, including habitat use, which is essential for amphibian monitoring programs. The goals of this study were to examine if detection probabilities were affected by bait (i.e., light and food), breeding activity, and environmental covariates in a population of fully aquatic salamanders, Necturus maculosus. I evaluated the effectiveness of three bait treatments (light bait, food bait, combined light and food bait) and an unbaited …
The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley
The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley
Theses, Dissertations and Capstones
Translocations have the potential to aim conservation efforts as well as to reduce mortality caused by human activities. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDB) have a limited ability to adapt to habitat loss and fragmentation due to the species’ slow life history and minimal dispersal ability. Because they are a venomous species, they are viewed as nuisance animals and are often killed on sight. We translocated a cohort of EDBs to investigate the potential of using translocations as a conservation and mitigation tool for this species. In July 2018, we translocated twelve adult eastern diamondback rattlesnakes from Parris …
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
Theses, Dissertations and Capstones
Coyotes (Canis latrans) are now found throughout North and Central America, but before European colonization were restricted to west of the Mississippi. Migration occurred in two major paths to the East; north over the Great Lakes (through Canada) and south below the Great Lakes. The location of these routes is significant because those migrating north interbred with the wolves that reside there. These hybrid animals are larger and behaviorally different from their western counterparts. It is possible to differentiate these hybrids morphologically and genetically. Hybrids are known to be located in Maine, New York, and Pennsylvania, but the interest of …
Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Telemetry Techniques And Translocation, Michael Thomas Jungen
Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Telemetry Techniques And Translocation, Michael Thomas Jungen
Theses, Dissertations and Capstones
Internal implantation of radio-transmitters is the preferred attachment technique for snakes, but the high costs and invasive nature of the surgery make a functional alternative desirable. External radio-transmitters are cost-effective alternatives to surgical implantation. Rattlesnake rattles are unique morphological features that can serve as an attachment site for external radio-transmitters. Using thread and epoxy, I attached transmitters to the rattles of eastern diamondback rattlesnakes (Crotalus adamanteus; EDB). I calculated average monitoring duration using radio telemetry data collected from 49 adult EDBs telemetered from 2014 to 2017 in coastal South Carolina. On average, we monitored EDBs for 189 ±78 days with …
Amphibians Among Road-Rut Pools In West Virginia, Abby L. Sinclair
Amphibians Among Road-Rut Pools In West Virginia, Abby L. Sinclair
Theses, Dissertations and Capstones
As anthropogenic environmental stressors such as urbanization continue to increase, it is necessary to understand their impact on amphibian ecology. Due largely to their biphasic life history amphibians are negatively impacted by the destruction of lotic habitats i.e., wetlands for the creation of roads and urban centers. I examined the effects of three human-made road rut pools on the reproductive success and species richness of amphibians in southwest West Virginia from May to October 2012. I employed three detection techniques: drift fence pitfall trap arrays, funnel traps and dipnet sampling. Additionally, habitat covariates were taken (i.e., water depth) at each …
The Life History Of Faxonius Rusticus (Girard, 1852) In Sunfish Creek, Monroe County, Ohio, Kyle Mcgill
The Life History Of Faxonius Rusticus (Girard, 1852) In Sunfish Creek, Monroe County, Ohio, Kyle Mcgill
Theses, Dissertations and Capstones
Crayfish are among the most imperiled faunal groups globally. The continued spread of invasive species is a major impact to crayfish. Invasive species, much like the native species, are often understudied. As declines continue, invasive species spread, and new species are discovered; additional life history studies are as important as ever for crayfish conservation. Life history data was collected for rusty crayfish (Faxonius rusticus) from October 2017 to September 2018 in Sunfish Creek, Monroe County, Ohio. Faxonius rusticus are native to the Ohio River drainage around Cincinnati, Ohio but have extensively expanded their range over the past 30 years. Sunfish …
Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker
Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker
Theses, Dissertations and Capstones
The brook trout (Salvelinus fontinalis) is facing many challenges throughout the Appalachian region, which are thought to be brought on by effects of climate change and the loss of habitat because of the disturbance from the pursuit of energy sources, namely, the mining of coal in the region. Most of the mining occurs in the central plateau and southern mountain region of West Virginia. The brook trout have historically had an expansive range covering this region and has the potential to inhabit the headwater stream systems that occur very prevalently throughout the Appalachians. In the state of West Virginia, the …
Natural History Of A Population Of Wood Turtles (Glyptemys Insculpta) In West Virginia, Jessica Curtis
Natural History Of A Population Of Wood Turtles (Glyptemys Insculpta) In West Virginia, Jessica Curtis
Theses, Dissertations and Capstones
The Wood Turtle (Glyptemys insculpta) is listed as vulnerable in West Virginia and only occurs in the Eastern Panhandle. The study population is unique in West Virginia because it occurs at a much higher mean elevation than other Wood Turtle populations in the state. The primary objective of this study was to determine if, and to what extent, altitude affected this population’s ecology. Turtles were located with opportunistic surveys and captured by hand. I located 31 turtles: 18 males, and 13 females. Turtles were captured a total of 68 times. Ratio of males to females did not differ significantly from …
Examining Habitat Selection And Home Range Behavior At Multiple Scales In A Population Of Eastern Box Turtles, (Terrapene C. Carolina), With Notes On Demographic Changes After 17 Years, Brian Anthony Williamson
Examining Habitat Selection And Home Range Behavior At Multiple Scales In A Population Of Eastern Box Turtles, (Terrapene C. Carolina), With Notes On Demographic Changes After 17 Years, Brian Anthony Williamson
Theses, Dissertations and Capstones
The Eastern Box Turtle, Terrapene c. carolina, is a terrestrial species native to the eastern United States. Once considered common, it is currently declining in much of its range due to habitat destruction and disease. To conserve the species, knowledge of Eastern Box Turtle habitat selection and the factors influencing their movement is necessary. Although the home range behavior of the Eastern Box Turtle has been well studied, few studies have quantified habitat selection at the home-range scale. Therefore, I examined home-range selection and within home range habitat selection in a population of Eastern Box Turtles at Hungry Beech Nature …
Filling In The Gaps In Phenology And Life History Of The Cumberland Plateau Salamander (Plethodon Kentucki), Robert C. Bowers
Filling In The Gaps In Phenology And Life History Of The Cumberland Plateau Salamander (Plethodon Kentucki), Robert C. Bowers
Theses, Dissertations and Capstones
The Cumberland Plateau Salamander, Plethodon kentucki, is a member of the Plethodon glutinosus complex comprising 16 sibling species, which are best differentiated by range. Few studies have been conducted to gain information on the natural history of P. kentucki. To alleviate this, two sites at Beech Fork State Park in Wayne County, West Virginia were used to study the salamander’s general life history with emphasis on reproduction, phenology, and population size. At each site, three 20m x 20m sample plots were arranged based on viability of the habitat for P. kentucki. Ground searches of all cover objects …
Dietary Preference Of The Queensnake (Regina Septemvittata), Timothy J. Brust
Dietary Preference Of The Queensnake (Regina Septemvittata), Timothy J. Brust
Theses, Dissertations and Capstones
The Queensnake (Regina septemvittata) is a small secretive water snake found throughout the eastern United States. Once common, their numbers have declined to the extent that they are now threatened throughout most of their range, largely the result of pollutant-based reduction in prey species. These snakes are assumed to eat molted crayfish exclusively. For some common crayfish species, molting happens only twice a summer during a two- week period. It has not been documented if Queensnakes eat anything besides crayfish on a regular basis. The purpose of this study was to determine the prey preference of Queensnakes with particular focus …
The Effect Of Auditory Call Playback On Anuran Detection And Capture Rates, Derek Adam Bozzell
The Effect Of Auditory Call Playback On Anuran Detection And Capture Rates, Derek Adam Bozzell
Theses, Dissertations and Capstones
Calls of male anurans during breeding seasons are species-specific identification tools. However, males cease calling after any nearby disturbance, including those of researchers. I proposed a variation on current methods that attempts to reduce this lag in calling after researcher-created disturbance by utilizing the propensity for competition in male frogs. I surveyed 14 breeding sites in Cabell and Wayne counties during the 2010 and 2011 breeding seasons. First, I used traditional visual encounter surveys (VESs). After using automated recording devices to gather site-specific recordings of calls of all species present, I conducted secondary VESs while playing these playlists over a …
Freshwater Mussel Populations Of The Monongahela River, Pa And Evaluation Of The Orsanco Copper Pole Substrate Sampling Technique Using G.I.S. Interpolation With Geometric Means, Jonathan Hart
Theses, Dissertations and Capstones
Large river studies for freshwater mussel populations and habitat in the Monongahela River within Pennsylvania have been almost non-existent over the past century. Aquatic diversity and water quality have been impaired in the Monongahela River since the Industrial Revolution and early impoundments were constructed to control the river. To date, there have been no thorough mussel population studies conducted on the Pennsylvanian Monongahela River proper since A.E. Ortmann in 1919. The mussel population accounts for this large river system are invaluable accounts of the aquatic condition of the Monongahela River. Mussel populations and habitat within the river have diminished drastically …
Effect Of Snake Populations On Salamanders As A Result Of Forest Fragmentation, Casey Renee Bradshaw
Effect Of Snake Populations On Salamanders As A Result Of Forest Fragmentation, Casey Renee Bradshaw
Theses, Dissertations and Capstones
Forest fragmentation is one of the main causes for the loss of native biodiversity. One consequence is increased proportion of edge habitat that introduces new “edge” species, and makes habitat for interior forest-living species less-suitable. This study was conducted at three sites in Tucker County, West Virginia and included one downhill ski slope, one cross country ski slope, and one gravel road. The main objectives of this study were to determine relative abundance of snake communities, how far species move from edge habitat into the forest and to determine whether snakes are a predatory threat to salamanders, specifically the federally …
Long-Term Growth And Monitoring Of The Eastern Hellbender (Cryptobranchus A. Alleganiensis) In Eastern West Virginia, Douglas Charles Horchler
Long-Term Growth And Monitoring Of The Eastern Hellbender (Cryptobranchus A. Alleganiensis) In Eastern West Virginia, Douglas Charles Horchler
Theses, Dissertations and Capstones
Amphibian declines have been well documented, specifically in the last few decades. The Hellbender, Cryptobranchus alleganiensis, one of North America’s largest salamander species, has suffered dramatic declines throughout much of its range, with estimated declines of up to 77 percent recently documented in some populations. With diurnal and nocturnal searches and mark-recapture techniques, I collected data on the status of Eastern Hellbender populations in Eastern West Virginia. We re-sampled a study site on the West Fork of the Greenbrier River that was first examined in 1998 by Jeff Humphries. Long-term growth and survivorship data were collected and compared to 1998 …
Distribution And Conservation Genetics Of The Cow Knob Salamander, Plethodon Punctatus Highton (Caudata: Plethodontidae), Matthew R. Graham
Distribution And Conservation Genetics Of The Cow Knob Salamander, Plethodon Punctatus Highton (Caudata: Plethodontidae), Matthew R. Graham
Theses, Dissertations and Capstones
Being lungless, plethodontid salamanders respire through their skin and are especially sensitive to environmental disturbances. Habitat fragmentation, low abundance, extreme habitat requirements, and a narrow distribution of less than 70 miles in length, makes one such salamander, Plethodon punctatus, a species of concern (S1) in West Virginia. To better understand this sensitive species, day and night survey hikes were conducted through ideal habitat and coordinate data as well as tail tips (10 to 20 mm in length) were collected. DNA was extracted from the tail tips and polymerase chain reaction (PCR) was used to amplify mitochondrial 16S rRNA gene fragments. …
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Theses, Dissertations and Capstones
Since 1971, documented Rough Greensnake (Opheodrys aestivus) occurrences in West Virginia have declined from approximately 100 to less than 20 occurrences in the last 10 years. In contrast to the decline of Rough Greensnakes in WV, Smooth Greensnake (O. vernalis) populations appear to be stable over the same period of time. Historic sites from the West Virginia Biological Survey were cross referenced with habitat descriptions in published literature to establish research locations. One hundred nineteen Rough and Smooth Greensnakes were measured for snout-vent length and total body length, and of these, 78 were measured in detail for external head morphology …
Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer
Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer
Theses, Dissertations and Capstones
The Eastern Hellbender, Cryptobranchus alleganiensis alleganiensis, is a species of concern in West Virginia and is in need of management. An important component of conservation efforts will involve identifying suitable habitat for protection. The goal of this research was to locate populations and examine hellbender habitat preferences to help managers identify habitat for protection. Populations were located using rock turning surveys from May through November, 2006. Hellbenders may be sensitive to water chemistry, so the dissolved oxygen, pH, turbidity, specific conductivity, and water temperature were measured. Substrate composition may influence populations, so substrate was characterized with Wolman pebble counts. …
Survey Of The Great Kanawha River, West Virginia, For Virulence Related Gene Markers Stx1, Stx2, And Eaea, Christina Carole Johnson
Survey Of The Great Kanawha River, West Virginia, For Virulence Related Gene Markers Stx1, Stx2, And Eaea, Christina Carole Johnson
Theses, Dissertations and Capstones
Microbial surveying using antibiotic resistant bacteria, fecal coliforms, and virulence genes is an approach not previously tested on the Great Kanawha River. Research objectives were to test antibiotic resistant and fecal coliform bacteria as bioindicators of water quality, and develop a multiplex- polymerase chain reaction (mPCR) system for identification of stx1, stx2, and eaeA DNA sequences in isolated fecal coliforms (FC). Fecal indicator populations and antibiotic resistant populations were demonstrated to be independent. Bacterial populations were assigned impact score(s) (IS) values for each sample site based on data set percent ranks. Population scores were summed per sample site to generate …
The Breeding Ecology And Natural History Of Ambystomatid Salamanders In An Ephemeral Wetland In Mason County, West Virginia, S. Douglas Kaylor

Theses, Dissertations and Capstones
A forested ephemeral wetland in Mason County, WV, documented to contain 4 of 5 Ambystoma species found in the state, was studied to learn about population sizes, breeding cycles, and habitat use. Minnow traps were placed along three drift fences with additional traps placed throughout the study area. From February 5 to March 27, 2005, 85 captured adults were identified to species, marked by elastomer injection for mark-recapture analysis, and measured for morphometrics. Larval salamanders were identified, staged, measured, and returned. Egg clutches were mapped and counted. Mark-recapture analysis suggests the A. texanum population size is between 635 and 735 …

Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Theses, Dissertations and Capstones
Plethodon glutinosus populations in West Virginia were looked at in three different elevations. Objectives were to determine if there is enough difference in elevation to cause different populations to vary in morphology and reproduction. Nine morphological measurements were taken to represent both size and proportional shape. Sexual dimorphism was found in all measurements only in low elevations, males being larger (p<0.001-p=0.041). Mean measurements between the three elevations showed significant differences (p<0.005) in all measurements excluding head width, tail length, and 3rd digit length. Salamanders were dissected; testes and vasa deferentia were removed from males and ovaries with follicles were removed from females. Results showed males in lower and middle elevations deposit spermatophores May-July. Low sample sizes in higher elevations provided inconclusive results. Females of lower elevations lay eggs early-mid summer. Middle and higher elevations results revealed a likely spring oviposition, or possibly a fall oviposition.
Status Of The Small-Mouthed Salamander, Ambystoma Texanum (Mathes) In West Virginia, Robert Fiorentino
Status Of The Small-Mouthed Salamander, Ambystoma Texanum (Mathes) In West Virginia, Robert Fiorentino
Theses, Dissertations and Capstones
Over the past 60 years little natural history information on Ambystoma texanum (Small-mouthed Salamander) has been collected in West Virginia, the eastern most location for the species. Three historical breeding populations of A. texanum have been documented in the state, but salamanders from 2 of these locations have not been documented for the past 30 years. Searches of historical sites and favorable habitat in Mason, Jackson, and Wood counties yielded no evidence for the presence of A. texanum, except for the known breeding site in Wood County. Information on time of breeding and egg development was collected at the Wood …
Determining The Genetic Distances Between Sub-Populations Of Aneides Aeneus In The Westvāco Wildlife And Ecological Research Forest, Andrew Nicholas Johnson
Determining The Genetic Distances Between Sub-Populations Of Aneides Aeneus In The Westvāco Wildlife And Ecological Research Forest, Andrew Nicholas Johnson
Theses, Dissertations and Capstones
Aneides aeneus, the Green Salamander, is a plethodontid species ranging from southern Pennsylvania to central Alabama and from eastern Mississippi to Maryland. Populations of Green Salamanders most often inhabit cliffs and rocky outcrops which are moist but not wet and shaded. The animal is listed as a species of special concern by the West Virginia Division of Natural Resources Wildlife Diversity Program. Genetic and reproductive isolation due to strict habitat preferences of the Green Salamander could be a factor in the decline of the species. Seventeen tissue samples were retrieved from five sites within the Westvāco Wildlife and Ecosystem …
Natural Succession Of Benthic Populations In Constructed Sediment Ponds And Ditches In Southwestern West Virginia, Robin E. Dolin
Natural Succession Of Benthic Populations In Constructed Sediment Ponds And Ditches In Southwestern West Virginia, Robin E. Dolin
Theses, Dissertations and Capstones
Strip mining causes major disturbances of the natural environment. One such disturbance is the creation of valley fills, which often fill in the headwaters of small streams. Runoff from these valley fills can cause heavy siltation as well as acid and heavy metal deposition downstream. One way to combat this problem is through the construction of sedimentation ponds, which slow down the flow of water so that sediment can settle out and water chemistry can be altered before the water is discharged into the stream. Since these ponds are, in effect, temporarily replacing small headwaters once present, the question is …
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Theses, Dissertations and Capstones
The central Appalachian region of the United States receives some of the highest inputs of nitrogen (N) due to acidic deposition in the nation. It is believed that these high could levels contribute to a decline in forest soils within the next 50 to 70 yrs. This study examines factors that influence spatial variability in N-treated and untreated watersheds of the Fernow Experimental Forest, Parsons, West Virginia. Within each of the two watersheds [WS4 untreated control, > 100 yr.; WS3 N-treated, acidified, clear cut, ~ 31 yr.], two 0.04 ha plots, one high N and one low N, were selected for …

Theses, Dissertations and Capstones
In West Virginia, as throughout its range, there is limited information about the life history of the cave salamander (Eurycea lucifuga). The purpose of this study was to describe the natural history of this species in West Virginia. The objectives of this study were to determine habitat selection of the cave salamander, to ascertain its environmental characteristics, and to study its reproductive and non-reproductive biology. Three study caves were located in Greenbrier County, West Virginia. All sites were examined at least once each month from May 1999 through April 2000. Caves were divided into three zones: entrance, twilight, …
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Theses, Dissertations and Capstones
By implementing a mark-recapture study, I investigated the ecology of three species of sympatric plethodontid salamanders (Aneides aeneus, Desmognathus ochrophaeus, and Plethodon glutinosus) on rock outcrops in the Westvaco Wildlife and Ecosystem Research Forest, Randolph County, West Virginia. By examining activity patterns, vertical stratification, and habitat preference for A. aeneus, D. ochrophaeus, and P. glutinosus, I attempted to offer some insight into how these sympatric species avoid competition on small, isolated rock outcrops. Twenty-one surveys, both nocturnal and diurnal, were performed between 11 May and 17 October, 1999. During this time, 89 salamanders, encompassing five species ( …
